An increasing number of fires are occurring with the rapid development of cities, resulting in increased risk for human beings and the environment. This study compares geographically weighted regression-based models, including geographically weighted regression (GWR) and geographically and temporally weighted regression (GTWR), which integrates spatial and temporal effects and global linear reg...
Stroke risk has been shown to display varying patterns of geographic distribution amongst countries but also between regions of the same country. Traditionally a disease of older persons, a global 25% increase in incidence instead was noticed between 1990 and 2010 in persons aged 20-≤64 years, particularly in low- and medium-income countries. Understanding spatial disparities in the association...
We tested the prediction that at coarse spatial scales, variables associated with climate, energy, and productivity hypotheses should be better predictor(s) of bat species richness than those associated with environmental heterogeneity. Distribution ranges of 64 bat species were estimated with niche-based models informed by 3629 verified museum specimens. The influence of environmental correlat...
BACKGROUND This study investigates the impact of tubewell user density on cholera and shigellosis events in Matlab, Bangladesh between 2002 and 2004. Household-level demographic, health, and water infrastructure data were incorporated into a local geographic information systems (GIS) database. Geographically-weighted regression (GWR) models were constructed to identify spatial variation of rela...
The translation of government work report (GWR) should not only be faithful to the spirit original text, but also close stylistic features target language and context. These correspond Ideational, Interpersonal Textual functions Three Meta-functions Theory, which is great research value in current circumstance beset by COVID-19. Taking 2020 GWR as material due its special social environment, th...
هدف: هدف این پژوهش مقایسه اثربخشی امیددرمانی و معنویت درمانی بر کیفیت زندگی، قند خون فشار زنان میانسال مبتلا به دیابت نوع دو بود. روش: حاضر نیمه آزمایشی با طرح پیش آزمون- پس پیگیری گروه گواه جامعه آماری شامل تمام 2 مراجعه کننده مرکز تحقیقات دیابت، متابولیسم غدد شهر تهران در سال 1399 بودند که 45 نفر شیوه نمونهگیری دسترس انتخاب صورت تصادفی آزمایش یک (هر 15 نفر) قرار گرفتند. ابزار پرسشنامه کوتاه...
We test exact and approximate Ginsparg-Wilson fermions with respect to their chiral and scaling behavior in the 2-flavor Schwinger model. We first consider explicit approximate GW fermions in a short range, then we proceed to their chiral correction by means of the " overlap formula " , and finally we discuss a numerically efficient perturbative chiral correction. In this way we combine very go...
BACKGROUND Deprivation indices are useful measures to analyze health inequalities. There are several methods to construct these indices, however, few studies have used Geographic Information Systems (GIS) and Multi-Criteria methods to construct a deprivation index. Therefore, this study applies Multi-Criteria Evaluation to calculate weights for the indicators that make up the deprivation index ...
BACKGROUND The primary aim of the study reported here was to determine the effectiveness of utilizing local spatial variations in environmental data to uncover the statistical relationships between West Nile Virus (WNV) risk and environmental factors. Because least squares regression methods do not account for spatial autocorrelation and non-stationarity of the type of spatial data analyzed for...
Remote-sensing data can be useful for investigating the bio-optical properties of the ocean. Among these bio-optical properties, chlorophyll-a content is of great importance. The standard NASA empirical ocean-colour (OC) algorithms are used widely to estimate global chlorophyll-a content. Despite their simplicity and effectiveness, these regression-based models have two shortcomings that we inv...
